Title: Stacker for veneer material
IPC: B65H31/24
Filed: 1972-02-03
Abstract: 1312220 Delivering sheets MOORE DRY KILN CO OF OREGON 3 Feb 1972 [22 Feb 1971] 5021/72 Heading B8R Sheets such as veneers 19, Fig. 1, are fed widthwise by a main conveyer 20 past a width detector 24 and thence over a plurality of bins 12, 14, 16, into a selected one of which each veneer is deposited under the control of diverting rollers 30, 32, 34 actuated by pneumatic cylinders operated by a controller 26. The veneers first pass a moisture detector 22 which together with the detector 24 are associated with the controller so that veneers of a certain moisture content are deposited in a bin 12, 14 or 16, while those of a different content pass to a further series of bins 18 &c. The bin 16 receives veneers of for example 54 inches, the bin 14 those of 27 inches, and the bin 12 narrow strips which are stacked in staggered formation to form a stack wider than the strips. The means for delivering strips to the bin 12 comprises two suction conveyers 46, 48, Figs. 1 and 6, each having two perforated bands passing suction chambers 96, 98. Suction is applied at one time to one of the conveyers such as 6 so that a veneer deflected by the roller 30 follows the conveyer and in so doing first triggers a switch 54 so as to withdraw a clamp 58, then triggers a switch 64 so as to project kicker arms 50 which remove the veneer from the conveyer so that it falls on to the support 36 against an aligning stop 60. As the switches are released, the clamp 58 secures the veneer against the support on the stack and the kickers are retracted. When the stack of strips against the stop 60 reaches a predetermined height, a switch 72 is actuated to reverse a valve and connect suction to the conveyer 98 so that following veneers are directed against a stop 74, switches 75, 77 causing similar actions, while the switch 82 reverses the suction and also actuates a pneumatic cylinder 40, Fig. 4, to lower the support by a measured increment. When especially thin veneers are sensed, arms 84 are moved into operative vertical position, Fig. 6, to direct such veneers straight down to fall on the centre of the stack. If an excessive number of strips are directed to the centre, a photo-electric device 94 inhibits action of the arms 84. The bins 14, 16, Figs. 1 and 14, are provided with only one vacuum conveyer 122, and the movement of the veneers is also guided by members 131 and 132 and leaf springs 130, similar members being associated with the bin 12. The supports 36 are convex at right-angles to feed direction to counteract upward curl of stacked veneers.

Title: Improvements in or relating to electrical condenser
IPC: H01G13/00
Filed: 1955-02-23
Abstract: 799,260. Making electric condensers. RADIO MATERIALS CORPORATION. Feb. 23, 1955 [April 5, 1954], No. 5404/55. Class 87(2). [Also in Group XXXVI] A number of electrical condensers is made by positioning a plurality of dielectric bodies 10 in spaced relationship, pressing or clamping against opposite sides of each body two terminals 11 each including a base 11b having yieldable means 11c bearing against but not attached to the dielectric body, and moulding a mouldable dielectric material such as a resin around each body and pair of bases while the terminals are so pressed or clamped. The dielectric sheath so formed serves to hold the terminals against the body (as described, against silver coatings on each end of the body). The sheath may be made of epoxy resin, with or without a mercapton-terminated polysulphide resin. Figs. 7 and 8 show a number of mould sections 18 clamped together to provide fourteen moulding cavities 18a in which fourteen condensers are made simultaneously, the resin being poured in liquid state through funnels 18b in the moulds. The assembled bodies and terminals are supported centrally in the mould cavities by slots 18g, Fig. 4, in which the shanks 11a of the terminals rest, the enlarged terminal bases 11b being disposed in the moulding cavities and the bodies 10 being held by spring tongues 11c on the terminals. Before the bodies and terminals are inserted in the moulds they are assembled in a jig, Figs. 2 and 3 (not shown). Prior to moulding, the liquid resin may be freed from air by vacuum. The mould assembly shown in Figs. 7 and 8, with the condenser parts and liquid resin therein, may be placed in a vacuum chamber for de-airing and then taken out and heated (or allowed to stand) to cure the resin. The moulds may be made of polythene and silicone separating agent may be used. Specifications 799,261 and 799,262 are referred to.

Title: Improvements in apparatus for cutting stone and like hard material
IPC: B28D1/02
Filed: 1956-02-22
Abstract: 805,136. Cutting stone. GRESSER, G. Feb. 22, 1956 [Feb. 24, 1955; Aug. 8, 1955], No. 5457/56. Class 124. Apparatus for cutting stone and like hard material by a rotary cutter comprises a pointer and a measuring scale one of which is attached to a traversable support for either the cutter or the workpiece and one of which is movable relative to the other while the support is stationary to determine the distance between successive cuts, and another pointer on the measuring scale, the latter pointer being adjustable relative to a zero mark on the scale to compensate for the thickness of cut. As shown, a saw blade and motor 1 is mounted on a support 2 on which it is traversable, and the saw blade may operate on a workpiece 4 on a table 5. A rigid bar 6 carrying an adjustable pointer S<SP>1</SP> is secured to the motor and participates in the movement thereof. A scale bar 7 is mounted on the apparatus directly below the bar 6 and has an adjustable pointer S<SP>2</SP> which may be adjusted to allow for the thickness of cut, the zero marks on the scale and the bar being coincident. In operation the pointer S<SP>2</SP> is set to the right of the zero a distance equal to the thickness of the cut and the pointer S<SP>1</SP> to the thickness of workpiece required. When a cut is completed the saw and motor unit is moved to the right to bring the pointers opposite each other and the next cut then started. During the second cut the pointer S<SP>1</SP> is again moved to the left by a distance corresponding to the thickness of the workpiece. In a modification, Figs. 5 and 6 (not shown) the scale may be in the form of a rotatable disc connected to the movable part by a rope. In a further modification, Figs. 7 to 11 (not shown) the bar and scale are replaced by tapes wound on drums.

Title: Control valve for central heating installation of the single pipe type
Inventor: KOPONEN TAUNO
IPC: F16K11/083
Filed: 1968-02-02
Abstract: 1,223,864. Valves. T. KOPONEN. 2 Feb., 1968 [4 Feb., 1967], No. 6490/68. Heading F2V. A valve, which is adapted for use with a heating installation of the single pipe type, comprises a housing 3 which is connectible to supply and withdrawal pipes 12 and to a radiator 11, the latter connection being by means of a connector 2, a valve slide 1 which has extending therethrough two passages 5, the passages extending from diametrically opposite openings 5<SP>1</SP> and terminating in openings 5<SP>11</SP> and 6<SP>11</SP>, the latter two openings being formed at the radiator end of the spool and being disposed on opposite sides of a baffle projection 7, and a connector element 4 which acts as a baffle for the direct flow between the two pipes 12 and which extends between the spool and two actuators 8 and 9. In operation, the spool may be rotated without axial displacement by handle 8 as a result of which flow to and from-ports 5<SP>1</SP> is restricted, such restriction resulting from the openings being blocked to a greater or lesser extent by arcuate portions (13, Figs. 2, 4 and 6, not shown), formed in the housing. Alternatively, flow to the radiator may be reduced by moving the spool axially but non-rotatably as by operation of a screw-actuator 9, the actuator being in screw-threaded engagement with the terminal portion of element 4. Simultaneous axial and rotational movement may also be imparted to the spool by operation of both the handle 8 and the screw 9. In a modification (Fig. 2, not shown), the screw operator 9 may be replaced by an actuating element which is connected to the terminal portion of element 4 and to a thermally responsive bellows (10), with the bellows being adjustable in axial extent.

Title: Improvements in and relating to testing materials by means of the transit times of ultrasonic impulses
Inventor: MARTIN HANS JOACHIM
IPC: G01N29/06
Filed: 1957-02-18
Abstract: 858,285. Ultrasonic inspection devices. ZEISS JENA C. VEB. Feb. 18, 1957, No. 5503/57. Class 40 (7). In an ultrasonic pulse-echo flaw detector for examining a cylindrical workpiece, the echo pulses are applied to intensity modulate the timebase of a cathode-ray tube which is synchronized with the pulse transmission and means are provided for displacing the transducer parallel to the longitudinal axis of the work-piece and for producing a relative rotary motion of the transducer and workpiece about said axis, the timebase being rotated in synchronism with said relative rotary motion. As shown in Fig. 1 the cylindrical workpiece 1 is rotated in a tank 3 containing coupling fluid 2 by means of a motor 4 coupled to a sine-cosine potentiometer 9 producing voltages which rotate the timebase of the cathode-ray tube (not shown) and the transducer 7 is displaceable longitudinally along a spindle 7. Alternatively the coupling fluid may be introduced by a nozzle attached to the test lead. When testing a hollow cylindrical workpiece 13, Fig. 2, the workpiece is fixed and the transducer 11, which is preferably cylindrical or spherical, is rotated about and displaceable along the axis 12 of the workpiece. The radial position of the display may be controlled by adjustably delaying the timebase with respect to the transmitted pulse and the scale of the display may be controlled by adjusting the magnitude of the deflection voltages. The receiver may include a limiter to prevent blurring of the image.

Abstract: 696,511. Volt - ampere measurement. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Jan. 21, 1952 [March 7, 1951], No. 5544/51. Class 37. The output of a transductor varies in accordance with voltage and current in a main A.C. circuit to operate a volt-ampere measurement or control device. In the 3-phase K.V.A. summator circuit shown the input winding 8 on the transductor T is energized with D.C. through a 3-phase rectifier R in accordance with the summated currents in the main circuitphase conductors 2, 3, 4. The transductor output windings 6, 7 are in series with the operating coil or element 1 of a meter M across the phase lines so that meter M is simultaneously phase voltage and current responsive and registers total K.V.A. A connecting line 9 between the star point of the secondary windings in the summating current transformers AT2-4 and the mid-point in the transductor input winding 8 ensures accuracy in summation with unbalanced loads. A reverse arrangement involves making the control winding responsive to voltage and the output windings responsive to this voltage and to a voltage variable with the main circuit current. The transductor may be provided with three separate control windings connected through separate rectifiers. A further embodiment utilizes n-transductors and an n-element meter for an n-phase system. The meter M may be of the thermal type and comprise a maximum demand indicator.

Title: Improved method and apparatus for electrically producing copying stencils
Inventor: LANT RICHARD
IPC: B41C1/14
Filed: 1951-03-08
Abstract: 709,809. Copying-telegraphy ; local copying by scanning. RONEO, Ltd. Feb. 22, 1952 [March 8, 1951], No. 5608/51. Class 40 (3) In a method of producing a perforated stencil by scanning an original with a light spot in association with a photo-sensitive cell and passing the derived current in the form of sparks through a stencil sheet disposed between electrodes, the current applied to the electrodes is caused to vary in approximately linear relationship to the density of the part of the original being scanned. The light received by the cell varies inversely as the antilogarithm of the density of the original and a circuit arrangement is included to provide an approximate logarithmic reduction of the signal from the cell. In the arrangement shown, light from a source 23 is reflected from the original carried on a drum 12 to a photo-cell 25 whose output is fed to a valve 31. The anode load of the valve 31 includes a resistance 32 and a resistance 33 connected to the positive side of a battery 34 and by a potentiometer 43 to a tapping on the battery. Three diodes 35, 36, 37 are connected in parallel with the resistance 33 and have variable resistances 40, 41, 42 connected to points on the potentiometer 43 providing adjustable biasing voltages for the anodes of the diodes. As the anode of the diode 37 is the least negative, this diode will be the first to conduct in response to a signal and will reduce the gain of an output valve 38. For signals of greater amplitude conduction in diode 37 will be accompanied by conduction in one or both of the diodes 35, 36 with further reduction in the gain ot the valve 38, which is operated on the anode bend of its characteristic. The grid of the valve 38 is also fed via transformer 39 with a carrier frequency derived from an oscillator 44 so that the output of the valve 38 is an amplitude-modulated carrier which is further amplified by valve 45 and passed via an output stage 47 to the tungsten electrode 29 associated with the stencil sheet on the drum 13 which forms the second electrode of the spark gap. The stencil sheet may include metal powder, graphite or carbon black so that it is opaque to light except where perforations have taken place and the perforated stencil is equivalent to a film transparency. The transmitting and recording drums 12, 13 as shown are driven from the same shaft 14, but the recorder may be operated at a distance from the transmitter, and controlled by synchronizing currents. The shaft 14 is preferably driven from an intermediate shaft driven from the motor through a centrifugal clutch brought into operation when the motor is set into operation. By this arrangement the shaft 14 is free for manual adjustment when the motor is at rest. The scanning and recording units are advanced step-by-step by a threaded nut engaging a screw shaft which is given a slight rotation at each complete revolution of the shaft 14.
